Hi footthumb,
When a problem is more of a technical issues, we are not supposed to discuss them here. This is a case for the support.
http://www.maxon.net/support/support-questions.html
The main reason is, that being handled by the support leads to an organized handling of the resulting data and with that a better feedback for the developers.
I assume you have both, the newest R16 update as well as the current Wacon software installed. Besides that, I change the cables at least ones a year, based on experience.
I work since years with Wacon (well way over a decade) and things have changed over the years, will say it got better and better. However, from time to time, after a new start, I noticed an old behavior, but pressing the 1,2, or 3 key while using the pen in the Editor View, seems to “calibrate” the tablet. [Mac]
All the best
From the Help Manual: (note that Windows and Mac are not comparable)
Graphics Tablet
If you experience problems when using a graphics tablet with CINEMA 4D, enable the Graphics Tablet option.
Tip:
Mac OS does not offer this (or the next) command. The functionality is activated automatically.
Hi-Res Table[
If you still experience problems and you are using the latest driver for your tablet, disable Use Hi-Res Coordinates to
use the tablet in mouse mode. Although you will lose some of the tablet’s resolution, you should barely notice the difference.
